Amphenol JT/LJT Subminiature Cylindrical Connectors MIL-DTL-38999 Series I and II
Amphenol LJT and JT Series subminiature cylindrical connectors are qualified to MIL-DTL-38999*, Series I
and II respectively. These connectors were developed to meet the needs of the aerospace industries, and provided the impetus for development of the MIL-C-38999 specifications, which recently
were superseded by MIL-DTL-38999. Meeting or exceeding MIL-DTL-38999 requirements, Amphenol® JT/LJT connectors feature: • Lightweight, Space Saving Design • Contact Protection -
100% scoop-proof LJT design prevents bent pins and short circuits during mating • Quick Positive Coupling - 3 point bayonet lock system • Mismating Eliminated - with 5 key/keyway
design • Error Proof Alternate Positioning - insured by different key/keyway locations • EMI Shielding - grounding fingers standard in LJT Series; optional in JT Series • Nine Shell
Sizes and a Variety of Shell Styles • Contact Options - size 8, 10, 12, 16, 20, 22M and 22D Crimp, Solder, PCB, Wire wrap, Coax, Twinax, Triax, Thermocouple, Fiber Optic and Filter •
Fixed Solder Contacts - per MIL-C-27599 • Hermetic - air leakage limited to 1 X 10-7 cm3 per second optional • Inventory Support Commonality - uses standard MIL-C-38999 contacts, insert
arrangements and application tools.
Where proof of high reliability and lot control is required, MS approved equivalents to most proprietary JT and
LJT connectors are available.
* MIL-DTL-38999 Series I supersedes MIL-C-38999 Series I. MIL-DTL-38999 Series II supersedes MIL-C-38999 Series II.
